2. Apex of the genital segment of the male nearly transverse, distinctly trisiuti- 

 ate, the outer apical angles acute; inhabits the northern States and 



Canada hilaris. 



Apex of the genital segment of the male quite deeply and subacutely eniargi- 

 nate, very obscurely sinuated, the outer apical angle obtuse ; inhabits 

 Mexico and the West Indies iiiarginata. 



Kezara peniisylvaiiica De Geer. 



This distinct species seems to be rare and local. I took one speci 

 men with the young at Woodbine, N. J., in August, 1902, and have 

 seen three others from the same State. Prof. D. S. Kellicott once 

 sent me an example captured in Ohio, and more recently Mr, Chag- 

 non has taken one at Montreal. Prof. Osborn records it from Iowa, 

 and Dr. Uhler from New Jersey, New York, Massachusetts and 

 Illinois, and Say's type (for abrupta) was from Georgia. Dr. Dist- 

 ant includes it in the Biologia material. 



:Vezara Tiridiila Linn. 



Dr. Uhler says that in the United States this species inhabits the 

 littoral plains from Virginia to Florida and Louisiana. It may be 

 roughly distinguished from the two following which it closely re- 

 sembles by the longer head, concolorous abdominal margins and the 

 short truncated osteolar canal. For the Westwood synonyms of this 

 species see Distaut's paper in Proc. Zool. Soc, 1900, p. 818. 



Xezara inarginata P. B. 



According to Dr. Uhler this southern species inhabits the coastal 

 region of southern Florida and Texas. I have seen a specimen 

 taken in Arizona by Prof F. H. Snow and another taken in Cali- 

 fornia by Mr. D. W. Coquillett, and Mr. Townsend has taken it 

 on Gercis in Arizona. 



Xezara hilaris Say. 



This is a showy but very common insect throughout the north- 

 eastern United States and Canada. Toward the south its range ex- 

 tends through the southern States and West Indies to Brazil. In 

 the West it occurs in Kansas, Iowa, Colorado, Montana, Utah, 

 Arizona and Texas, and perhaps over all the western States. This 

 is a larger species than marginata, and is more oblong in form with 

 the apex of the scutellura more slenderly produced. The form of 

 the male genital segment is quite distinctive and will at once dis- 

 tinguish the species.
